VEHICLE WHEEL CONSTRUCTION.

Specification of Letters Patent.

Application filed July 16, 1914. Serial No. 851,237.

T all whom it may concern Be it known that I, EMIL O. LINDNER, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and y useful Improvements inv Vehicle Wheel Constructions, of `which the following is a specification, such as will enable those skilled in the. art to which it appertains to make and use the same.; i A `This invention relates to wheel constructions for vehicles of any class, and the object thereof is to provide a wheel of this classso constructed that the same will act as a shock absorberzas well asanordinary wheel, and also possess the qualities of a spring or elastic wheel, and pneumatic tire.

The invention is fully disclosed in the fol-` lowing specification, Of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which vFigure 1 is a sectional side view of one form of wheel showing my improvement appliedY thereto; Fig. 2 ar section on the line 2 2 of Fig. l; Fig. 3 a View similar to Fig. 2 showing onlya part of the construction and showing a modification; and Fig. l a section on the line 4 4 of Fig. 3.

In Figs. l and 2 of the drawing, I have shown at a a main outer wheel member oomposed of separate outer and inner side platesI a2'and a3, each of which are provided with a circular hub flange at, and the inner side plate a3 is provided with a rim member n, the inner surface of which is provided with a groove o, and the plates a2 and a3 of the main Outer wheel member a are secured to gether by bolts al which are passed through the rim member a5.

Mounted within the hub flanges a* are annular bearing holders Z9 and b2 which are lL-shaped in cross section and each of which is provided with a4 detachable outer plate b3, and mounted between the bearing holders b and 52 and the hub flanges o* are bearings c and o2 which may be of any desired form.

rThe bearing holders 5 and 52 are provided with elongated slots b4 throughwhich passes a fixed angular axle shaft Z and the outer end of said axle shaft is provided with a spindle d2 and nut da and a flanged collar CZ* is secured to the axle shaft as shown at clit and inwardly of the wheel and by means Patented Apr. 2r?, 1915.

and said shaft is permitted to moveV vertically in the bearing holders 5 and? b2.

\ The rim member t5` is provided with a flexible tire e and in the construction shown said tire is held in place by flanges e2 on the wheel member o and by bolts e3, but the tire may be secured to the rim member a5 in any desired manner, and the hub flange atof the plate a3 is provided witha gear os by means ofvwhich saidwheel member a may be rotated, in the usual or `any desired manner.

The parts a toc3 inclusive are of the usual general construction with the exception of the specific design shown, andin the practice of my invention, I place on the axle shaft spindle d2 between the bearing holders b and Z22, a rotatable inner wheel f which may `be of any desired construction, and placedin. the groove a of the rim member a5 is a flexible rubber tube g provided with an air valve g2.

In the drawing, the wheel-1c is shown bearing on the tube g at the bottom thereof and to an extent suiiicientto support the load of the vehicle, and initheV operation of said vehicle should the wheel strike an `obstruction the wheel f would depress the tube g to a 'greater or less extent thereby acting as .a shock absorber.V

In Figs. 3 and 4t, I have shown a modi-i` flcation vin whichthe inner surface" of the rim member a5 is made straight in cross section and in place of the rubber tube g, I employ an elastic tube t and a metal band z' provided with side Iianges i2 by means of which the tube L is held in connection with said band, and the metal band may or may not be secured to the rim member a5, and the band z' is also provided with projections 3 which engage corresponding recesses in the rim member (1,5 to insure the rotation g y .i 1,137,154

j seen that the Vparts b Y A.

f hub members'which are-'radially movable onV thek axle, ror the spindle thereof, and theV invention is not limited to this arrangementV `qualitiesV of Yvv'heelsoi' the vclass specified. FromY the foregoing description it Will be b2 yand Z13 form side main outer Wheel member (iv is mounted on these side hub membersv and rotatable thereon. I y

'Y A In the accompanying drawing the cushion member is shown connected with the outer Wheel member, and this feature is so describedbut it Will be understood that my and if desired the cushion member may be connected With the inner Wheel member Without materially altering the construction, operation and result, and other changes in and modications ofthe construction herein describedmay be made, VWithin the scope of the appended claims, Without departing from the spirit of my invention or sacriicing its- 7'" advantages.

Having 4:fully: described my invention,

what I claim Vas new andl desire to secure by.` Letters Patent,is;- l. A Wheell construction, comprising a lixed axlefhaving -a spindle,"opposite side Y Yso hub members radially movable on said spindle, a main Wheel member mounted on said hub members'and rotatable thereon, and a' Y supplemental inner Wheel member mounted on said spindle and inclosed by said hub Y .members and the main WheelV member.

v2.v A Wheel construction, comprising a fixed axle having a spindle, opposite side j hub members radially movableon said spindle, av main Wheel member mounted on said main Wheel ymemberbeing provided Within the outer portionV thereof With a flexible tube on which the inner supplemental Wheel member is adapted to bear.

3. A Wheel construction, comprising a fixed axle having a spindle, opposite side hub members radially movable on said spindle, a main Wheel member mounted on said hub members and rotatable thereon, and a supplemental inner Wheel member mounted on said spindle, said main Wheel member being provided Within the outer portion thereof with a flexible member on which the l inner supplemental Wheel member is adapted to bear.

4. A Wheel construction, comprising a fixed axle having a spindle, opposite side hub members radially movable on said spin dle, a main Wheel member mounted on said hub members and rotatable thereon, a supplemental inner Wheel member mounted on said spindle, said main Wheel member being provided Within the outer portion thereof with a iexible member on which the inner supplemental wheel member is adapted to bear, and means for holding said flexible member in place.

5. A Wheel construction, comprising a fixed axle having a spindle, opposite side hub members radially movable on said spindle, a main'vvheel member mounted on said hub members and rotatable thereon, and a supplemental inner Wheel member mounted on said spindle, said main Wheel member being providedv on its outer face portion with a iiexible member.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing Witnesses this V15th day of July 1914.
